Angels stuff

Angels related idea I have yet to come up with a name for.

A postapocaliptic world in which at some point gods created several immortal beings who were supposed to govern over humans and disappeared soon after.  The angels soon became lost without their creators and many conflicts arose between them, eventually ending in a full blown war which ended with the death of the fighting sides leaders. Even after the war their problems didn't stop, just changed into more complex political intrigues.
